A coupling having at least two concentric rings, each having a circumferential surface and a recess, and at least two roller elements. The roller elements are each disposed in a channel formed by the circumferential surface of one of the rings and the recess of another of the rings. In some example
A coupling having at least two concentric rings, each having a circumferential surface and a recess, and at least two roller elements. The roller elements are each disposed in a channel formed by the circumferential surface of one of the rings and the recess of another of the rings. In some example embodiments of the invention, the coupling includes a coupling member with a bearing surface, at least one of the rings includes a split and the split ring is urged against the bearing surface when there is relative rotation between the rings. The coupling member is, for example, a shaft or a gear.

1. A coupling comprising: at least two concentric rings, each comprising a circumferential surface and a recess;at least two roller elements, wherein each of the roller elements is disposed in a channel formed by the circumferential surface of one of the rings and the recess of another of the ring;
1. A coupling comprising: at least two concentric rings, each comprising a circumferential surface and a recess;at least two roller elements, wherein each of the roller elements is disposed in a channel formed by the circumferential surface of one of the rings and the recess of another of the ring; anda coupling member with a bearing surface,wherein at least one of the rings has a split formed therein, and is urged against the bearing surface when there is relative rotation between the rings, andwherein the roller elements comprise respective circumferential surfaces that contact one another when there is relative rotation between the rings. 2. The coupling of claim 1, wherein the coupling member is a shaft or a gear. 3. The coupling of claim 1, wherein relative rotation of the rings adjusts a radial position of at least one of the roller elements. 4. A coupling comprising: at least two concentric rings, each comprising a circumferential surface and a recess;at least two roller elements, wherein each of the roller elements is disposed in a channel formed by the circumferential surface of one of the rings and the recess of another of the ring; anda coupling member with a bearing surface,wherein at least one of the rings has a split formed therein, and is urged against the bearing surface when there is relative rotation between the rings,wherein relative rotation of the rings adjusts a radial position of at least one of the roller elements, andwherein a first one of the roller elements is adjusted radially inwardly and a second one of the roller elements is adjusted radially outwardly. 5. A coupling comprising: at least two concentric rings; andat least three rollers arranged in a radial space between the rings,wherein the rollers are disposed in a first torque path beginning at a first one of the rings, extending through a first one of the rollers and a second one of the rollers, and ending at another one of the rings, when there is relative rotation between the rings along a first direction, andwherein a third one of the rollers is disposed in a second torque path beginning at the first ring, extending through the first roller and the third roller, and ending at the another ring, when there is relative rotation between the rings along a second direction, opposite the first direction. 6. The coupling of claim 5, wherein the rings comprise recesses and circumferential surfaces, and the rollers are disposed in channels formed by the recesses and the circumferential surfaces. 7. The coupling of claim 6, wherein at least one of the rings has a split formed therein and a friction surface, and relative rotation of the rings adjusts a radius of the friction surface. 8. The coupling of claim 7, further comprising a coupling member with a bearing surface, wherein adjustment of the radius engages the friction surface and the bearing surface. 9. The coupling of claim 8, wherein the coupling member is a shaft or a gear. 10. The coupling of claim 5, wherein the rollers comprise respective circumferential surfaces that contact one another when there is relative rotation between the rings.
